This controller has only a single gas fire control function and must be used in conjunction with the fire alarm controller. The fire
detector is connected to the fire alarm controller. When a fire occurs, the fire alarm controller will receive the fire alarm signal from the
fire detector or manual alarm button and issue instructions to the gas fire extinguishing controller. Then the gas fire extinguishing

Start mode of gas fire extinguishing
The pipe network gas extinguishing system has three starting modes: automatic control, manual control
and mechanical emergency operation.

The fire extinguishing device of the prefabricated gas fire extinguishing system is set in the protection zone, and personnel must be
evacuated in case of fire. Therefore, the prefabricated gas fire extinguishing system (fire extinguishing system without pipe network
) has only two starting modes: automatic control and manual control
The fire extinguishing device of the prefabricated gas fire extinguishing system is set in the protection zone. In case of fire,
personnel must evacuate.

the first fire alarm signal is issued, start the
fire audible and visual alarm in the protection
area; when the other fire alarm signal is
issued, confirm the fire alarm information,
start the fire audible and visual alarm outside
the protection area, and issue the linkage
control signal at the same time. After a delay
